I've attached pictures of this bucket on that's on the side of my pool. Pool came with the house so have no clue what it is. The inlet appears to be blocked off but has a very small leak so water trickles in. First year, the bucket just always stayed filled with water and we ignored it. Well, it froze and bucket cracked. Now water is seeping below the bucket. This is concerning. I have no clue what is feeding the supply line. I've turned off pump and it still trickles. Anyone have any ideas?
